ASTM/AISI Standard Alloy Round Bar
AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint.

General Scope
This grade is similar to 4140 in scope which has a higher carbon level giving 4130 an advantage when it comes to weldability, this weldability is achieved at the cost of through section hardenability.
AISI 4130 steel is a low alloy steel that is used in structural designs that may be found in applications such as aircraft engine mounts or welded tubing. It is well known for its ease of welding and ability to harden in commercial applications. It is commonly referred to as chromium-molybdenum steel.
Hot Rolled Steel Bar
Hot rolled steel bar is made of low carbon steel and ordinary alloy steel at high temperature. This production process makes the steel bar have high strength, excellent plasticity and toughness, as well as good corrosion resistance. The main characteristics of hot rolled reinforcement are its high tensile strength, wear resistance, good impact resistance, so it has a good bearing capacity. In addition, hot rolled steel bars can also be deformed by cold processing to meet different construction site needs.
Cold Rolled Steel Bar
Cold rolled steel is produced by a rolling metal forming process where the metal stock passes through one or more pairs of rolls to provide uniformity and reduce the thickness of the metal. If the temperature of the metal being rolled is below its recrystallization temperature, the process is called cold rolling.

Cold rolled steel bar is a kind of steel product made by special processing process. It conducts cold processing process such as cold pull and cold pull at room temperature, so as to obtain more accurate size and excellent physical properties. This reinforcement usually exhibits high strength, high hardness and good corrosion resistance, making it outstanding in various engineering applications. The surface quality of the cold roll round bar is very good. After the cold rolling treatment, the surface flatness is high and smooth without distortion, which makes its bonding ability with concrete stronger and improves the stability of the overall structure. In addition, the cold rolled steel rod also has good ductility and toughness, although its ductility is slightly worse compared to the hot rolled steel bar, but it can still maintain good performance under high strength load.
Cold Rolled Steel Bar Characteristics
Surfaces are more finished and tolerances are tighter.
Cold rolled steel bars are true and square, with sharp edges and corners.
Smooth surfaces tend to feel greasy.

The standard rebar threaded coupler is suitable for connecting two bars of the same diameter, where one bar can be rotated. It comprises an internally threaded sleeve with two right hand threads which are tapered towards the middle of the coupler. The bar ends are square cut and thread is onto the bar. A nominal allowance of +25mm should be allowed per threaded bar end for square cutting the bar end.
The couplers are generally torqued onto the reinforcing bar in the bar threading shop, the internal threads protected by plastic end caps. The threaded ends of the continuation bar are protected by plastic thread protectors.
